Density is measure as mass/volume. As with any matter, the density of chalk would require:
1. a measurement of its mass
2. a measurement for its volume.
Mass can be measures on a scale in kg. Chalk's shape also makes it calculable for volume (in metres). If it is cylindrical, measure the height and the radius, then solve for V = (pi)(r^2)h. Divide the mass by that volume and find its density in kg/m^3.
To measure the density of chalk, you need a sample of chalk, a scale to weigh the sample, and a graduated cylinder or measuring cup for volume measurement. First, weigh the chalk to determine its mass, then submerge it in water to measure the volume displaced, which corresponds to the chalk's volume. Finally, calculate the density using the formula density = mass/volume.
To find the number of chalk molecules it takes to write your name on the board, first measure the length of your name in centimeters. Next, estimate the thickness of the chalk line you would draw, then calculate the volume of chalk used by multiplying the length by the thickness. Finally, divide this volume by the volume of a single chalk molecule to determine the total number of molecules needed. You may need to use the density of chalk and the molecular weight to find the volume of one molecule.
A handful of chalk typically weighs between 100 to 200 grams, depending on the size of the hand and the amount of chalk taken. This is roughly equivalent to 0.1 to 0.2 kilograms. However, the exact weight can vary based on the density and type of chalk being used.
calculate density of sponge ?
Mass = Density -------- volume
about 1.1
Chalk powder is denser than oil, so it will sink when added to oil. This is because the density of an object determines if it will float or sink in a liquid - objects with a higher density than the liquid will sink, while objects with a lower density will float.
u find chalkunderground
Snow is cold Chalk tastes bad.
Chalk can be broken into pieces.
chalk has a greater density than water ans also chalk has a low surface tension
Dover.
yes it sinks because it doesn't have air inside so it doesn't float
The chalk float inside the water because chalk has a lower density than water, causing it to float. This is due to the principle of buoyancy, where an object will float if it is less dense than the fluid it is placed in.
maybe it might be near the chalk on the board
No, chalk is denser than salty water. Chalk is a solid mineral composed of calcium carbonate, while salty water is a liquid mixture of water and dissolved salt. The density of chalk is greater than that of salty water, causing chalk to sink in salty water.
No, natural chalk found in nature is formed from the shells of marine organisms, while chalk used on chalkboards is typically made from gypsum or calcium sulfate. The chalkboard chalk is designed to have a smooth texture and be easily erased from chalkboards.
